' This invention relates generally to flying machines, and has more particularreference to a novel aeroplane capable of resisting tail slipping or spinning or other dangerous and undesirable flying features. 4

The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, desirable and efficient in action, and which can be manufactured and sold .at a reasonable cos he invention proposes the use of opposite and pivoted chute wing portions on the main wings ofa flying machine transversely arranged relative to the fuselage, and opposite and pivoted chute wing portions on the four sides of a chute roof structure attached to the machine preferably above the said main wings. These chute wing portions should be arranged for simultaneous movements for assuming positions normally having little head-on resistance,. and quickly movable to positions for adding to stabilize the machine preventing a spin or breaking a spin.

As is generally known one of the greatest dangers in modern flying is that of falling into a tail spin especially while taking oif or landing. Many attempts have been made to remedy this shortcoming, but have failed in providing a simple structure readily adapted for performing its function. The positioning and operation of the said chute wings constitute the organization used in bringing out the principles of the invention.

For further comprehension of the invention,-and of the objects and advantages there of, reference will be had to the following description and accompanying drawings, and to t e appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing, forming a material partof this disclosure r- Fig. 1 is a perspective view'of an aeroplane constructed according to this invention.

the

Fig. 8 is a fragmentary edge view, as seen looking Fig. 6.

The referencenumeral 10 indicates generally the main wings of a flying machine having a fuselage 11 with a motor driven proin the direction of the line 8-8 of peller 12, a landing gear 13, a stabilizer 14:,

afin 15, a rudder 16 and elevators 17 arranged and connected for operation as is common on present day machines. A tail skid 18 is normally held in raised position by a spring 19, and may be lowered to operative position upon landing by drawing wire 20 extending Within reach of the pilot. The wings-10 are provided with customary ailerons 21.

Chute wing portions .22 are pivotall y mounted onthe wings 10 on the front and rear edges thereof, and on opposite sides of the fuselage 11,- and arranged for assuming normal positions in the plane of the wings l0, and movable downwards out of this plane.

A chute roof 23 is supportedby vertical rods 24 above the wing 10, and is of rectangularshape. On the four sides thereof chute. wing portions 25'and 26 are attached. The wings 25 are. on opposite sides and have straight ends, and the wings 26 are on opposite sides and have inclined ends for forming a hollow 27 when all of the wings are lowered.

Extending longitudinally relative to the fuselage 11, and between the rods 24 are walls 28, hinged at their centers as at 29 to the roof 23 and made of two sections arranged for swinging in a plane parallel with the roof 23 as indicated by the dot dash lines 30 in Fig. 6- and in Figs. 7 and 8. Links 31 pivotally connected with the wings 26 have elongated 4,

eral drums 37, an with a ratchet'wheel 38 heldagainst rotation by a spring pressed pawl 39 having a releasing handle 36. A plurality of flexible members 40 connect the various pivoted chute wing lowering the chute wings upon'clockwise ro-v tation of the shaft 35 as seen in Fig. 4,,and for. raising the chute wings upon anticlockwise rotation.

ortions with the drums and are arranged or simultaneously In operation of the device, the pilot operates wheel 36 for lowering the chute wings 22, and 26 simultaneously to inclined positions forming hollows or pockets for holding the machine against tail spinning or the like. Simultaneously with the moving of the wings 26, the walls 28 are moved, adding to the head-on resistance and stability of the machine when desired, that is in lowered po-- sitions of the chute wings. Wings 22, 25 and '26 are termed chute wings since they form a chute or passage, in this case, for air.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit'myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the inventionas defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. In an aeroplane of thevclass described, main wings, chute wing portions pivoted on the opposite front and rear edges thereof, and on opposite sides of a fuselage connected with the said main wings, a rectangular roof secured above the said main wings, chute win portions pivoted on the edges thereof, an means for simultaneously moving all of the said chute wings.

2. In an-aeroplane of the class described, main wings, chute wing portions pivoted on the edges thereof, and on opposite sides of the fuselage connected with the said main wings, a rectangular. roof secured abovethe said main wings, chute wing portions pivoted on the edges thereof, and means for simultaneously moving all of the said chute wlngs.

3. In an aeroplane of the class described, main wings, chute wing portions pivoted on the opposite front and rear edges thereof, and on opposite sides of the fuselage connected with the said main wings, a rectangular roof secured above the said main wings by means of verticalrods, and chute wing portions piv- .oted onthe edges thereof, and means for simultaneously moving all of the said chute wings. I a

4. In anaemplane oftheclass described,

main wings, chute, wing portions pivoted on the opposite front and rear edges thereof, and

-on opposite sides of the fuselage connected with the said main wings, a rectangular roof secured above the said main wings, chute Wing portions pivoted on the edges thereof, and

means for simultaneously moving all of the said chute wings, certain of the second mentioned chute wing portions having inclined ends.

6. In an aeroplane of the class described,

- main wings, chute wing portions pivoted on the opposite front and rear edges thereof, and on opposite sides of the fuselage connected with the said main wings, a rectangular roof secured above the said main Wings by means of vertical rods, and chute-wing portions pivoted on the edges thereof, and means for simultaneously moving all of the said chute wings, and walls being positioned longitudinally relative to the fuselage and between the said rods, and adjacent the said roof.

7. In an aeroplane of the class described, main wings, chute wing portions pivoted on the opposite front and rear edges thereof, and on opposite sides of the fuselage connected with the said main wings, a rectangular roof secured above-the said main wings by means of vertical rods, and chute wing portions pivoted on the edges thereof, and means for simultaneously moving all of the said chute ,wings, and walls being positioned longitudinally relative to the fuselage and between the said rods, and adjacent the said roof, and arranged for motion simultaneously with the said chute wings for adding to the head-on resistance oflthe aeroplane in lowered positions of the. chute wings.

.In testimony whereof I have afiixed'my signature.
